IMPROVEMENT IN SlNK-STRAINERS.

Specification forming part of Letters Patent No. 125,322, dated April 2,1872.

To all whom it may concern:

Be it known that I, JORDAN L. MoTT, of Mott Haven, in the county ofWestchester and State of New York, have invented a new and ImprovedSink-Trap; and I do hereby declare that the following is a full, clear,and exact description thereof, which will enable others skilled in theart to make and use the same, reference being had to the accompanyingdrawing forming part of this specification.

My invention relates to an improvement in the kind of traps that areapplied to sinks, and having the perforated plate at the top madedetachable for affording access to the trap' for cleaning it; and itconsists in having said plate hinged to the part supporting it, so thatit can be opened by swinging upward on the hinges, the object being toprevent the misplacing and losing of Vthe said plate, so often occurringwhen they are made detachable. The invention also consists in a novelconstruction of the hinge which I use for connecting the said plate toits supporting-plate, all as hereinafter described.

Figure l is a sectional elevation of my improved trap. Fig. 2 is apartial plan view of the ring which supports the perforated plate. Fig.3 is a plan view of the top of the perforated plate, and Fig. 4 is aplan of the trap with the perforated plate removed.

Similar letters of reference indicate corresponding parts.

A is the pan of the trap, with the collar or ring B extending above thebottom around the escape-passage, and with the annular recess c, inwhich the metal ring D rests, and is secured by screws or other means. Eis the perforated plate or riddle employed for separating the particlesof solid matter from the water as it passes oli', which plate is fittedinto the annular recess F of ring D, and it carries the inverted cup G,which extends below the top of B and forms the trap, together with saidextension B and the pan A. Heretofore this plate has been merely laid inthe recess F, to be lifted out and laid aside when the trap was to becleaned out, being frequently mislaid and lost, and liable to be letfall and broken 5 also being frequently left out of place, allowing thetrap and pipe below to get clogged up. Now l propose to have this platehinged to the ring l) to avoid these obstructions; and while I may usefor this purpose any suitable hinge, I prefer to employ the one hereshown, which I have specially devised for the purpose. Said hingeconsists in theV projection ti, on the edge of the plate E, the curvedrib of plate l) at the bottom of a recess, K, in the inner edge of ringD, and the stud L rising up from the upper surface of the part A, thesaid projection H having the groove I in the upper surface and the plainextension M outside of the groove, all as shown. The flange H isintroduced below the curved rib J in the recess K, so that the said ribis in the groove I before the rin g D is screwed down. Ihis brings thebottom of the dang-e so near the upper ends of the studs L that itcannot escape from under the rib J after the ring D is screwed down, andthe extension M of said flange comes against the studsL when the .plateE is raised, and prevents it from swinging too far back beyond avertical plane, beyond which it is allowed to pass only so far as isnecessary for its gravity to hold it open.

Having thus described my invention, I claim as new and desire to secureby Letters Pat' ent 1. In a sink-trap the perforated plate E, so hingedto the ring D as to prevent its removal without disturbing said ring, inthe manner and for the purpose specilied.

2. rIhc pan A, having the collar or ring B extending above the bottomand around the escape-passage so as to form a trough therein, incombination with the hinged perforated plate E, ha ving on. its underside the inverted cap G, as and for the purpose specilied. Y
